I've been having this same problem since Wednesday afternoon (worked fine in the morning) and have also done absolutely everything, including deleting/reinstalling, which took over four hours, and rebuilding my database, which kind of messed up everything on my console and now I have to fix all that in addition to the problems with this game that are still happening. It's really frustrating losing days on a sub I have to keep paying for.

It's not my WiFi, it's not PSN, it's this game specifically and only this game.
